Pilot-Cosmonaut, Hero of the Soviet Union since 1984, Igor Volk, has passed away at the age of 80 on January, 3, 2017. He was accepted to the cosmonaut detachment in 1978.He was of the generation of the legendary Soviet space explorers.
Igor Volk also personally observed a UFO, and discussed his experiences in the Russian media. The sighting was on Earth, not in space. It was a rather dramatic encounter; I have been working on a new article about Russian cosmonauts and UFOs, and the episode will be described there in greater details.
Rest in peace, Igor Volk. Вечная память!
